Problem with linked list ADT and incomplete structure

Hi,

I am having trouble with a linked list ADT implemtation that uses incomplete structures ie pointers to structures. The code for this ADT was provided for us and I can't get it to work/compile. The assignment was to use the provided ADT to manipulate linked lists. I have created another linked list ADT's that works but doesn't use incomplete structures. It is being very difficult to explore this usage when the provided code doesn't work.

Below is the code that was provided to us as a working example but it doesn't

Any help with what is wrong with the code or other examples of similar implementaions would be greatly appreciated.
